Sand casting. The cope and drag (top and bottom halves, respectively) of a sand mold, with cores in place on the drag. Two sets of castings (bronze and aluminium) from the above sand mold. Sand casting, also known as sand molded casting, is a metal casting process characterized by using sand — known as casting sand — as the mold material.

During mixing, water is absorbed between the clay platelets, clay swells and generates the ability of sand to be compacted. It is developed and controlled in the muller by the addition of water to the clay sand mixture. When expanded sand is compacted inside a confined space, the volume decreases and this is measured by reduction in the length.
